# Verify the <code>machine</code> attribute is now <code>pc-0.11</code> e.g.

+

#:<pre>

+

#: <os>

+

#: <type arch='x86_64' machine='pc-0.11'>hvm</type>

+

#:</pre>

+

# Start the guest and verify that it boots correctly as before

+

+

That's it! The idea is that we record the ABI version number of the <code>pc</code> machine type in the guest configuration so that when qemu is updated in future, we will continue using the same ABI.
